Crimson charms are used in Summoning to summon certain creatures. The amount of experience gained from each charm used varies between 83.2 and 1015.2 depending on the pouch made, making crimson charms the second most powerful charm after blue charms. Crimson beats out blue in one aspect — creating a Talon beast pouch using a crimson charm gives 1015.2 experience, the highest of any pouch. However, talon beast charms, which are required for the pouch, can be time consuming to obtain.
